CULTIVATOR-PLO.

SPECIFICATION forming part of Letters Patent No. 299,160, dated May 27, 1884:.

Application filed November 14, 1883. (No model.)

provements in Cultivator-Flows; and I do.

hereby declare the following to be a full, clear,

. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to cultivators, partic: ularly that class termed sweeps-a wellknown plow in the cotton belt-and is intended for use principally in the cultivation of corn and the cotton and tobacco plants.

The invention consists of a plow-blade, or sweep, as it is termed, secured to the end of a handled beam, and a series of cutting teeth or colters arranged upon a triangular frame and secured to the beam immediately in front of the sweep; and the particular points of invention are a novel construction of the colters and mode of attachment to their frame, as also the means bywhich the said frame may be adjusted vertically to regulate the depth of cut of said colters, and in details of construction of the several parts, whereby to accomplish the desired result, as will be hereinafter more particularly explained, and pointed out in the claims.

Referring to the drawings accompanying this application, and in which similar letters of reference indicate like parts in the several views, Figure 1 represents a plan, and Fig. 2 a side elevation, of a cultivator constructed according to my invention; Fig. '3, a vertical sectional side elevation, and Fig. 4 a front View, of the same. views, in elevation and section, of one of the colters, showing the construction of the same and its mode of attachment to its frame.

A is the plow-beam, which may be of the usual or any approved form, having the handles B B, which are secured, as usual, to the beam by a through-bolt at their ends, as at a, and a brace, O, which in this instance is composed of a narrow flat metal strip, one end being secured to the end of the beam at the top thereof, as at G, and then, after passing upward and around the cross-brace D of the han- Fig. 5 represents detached dles, its other end is also secured to the top of the beam slightly in advance of the first end, as at (Z. A rivet, c, secures the brace around the cross-brace D of the handles. By this means the handles are securely braced up in proper position, and always remain in this position, no matter at what gage or angle the plow may be set.

E is the standard, united to the beam by a yoke, E, having adjustment-holes e therein, and abolt, e, passing therethrough and through the beam A. forward, and carries at its foot, wherein a slot, F, is formed, the plow or shovel G, which is made somewhat thicker at its central or point portion, as shown at G, than at the wings, through which the securing-bolt II is inserted, and passes through the slot F in the standard. The plow, or sweep G, as it is called, is of the V form, and by increasing the thickness at the point G the portion subject to the greatest wear is strengthened, and greater security is given to the bolt. The slot F in the standard is to permit of the adjustment of the blade to gage the depth of the cut thereof, and by adjusting the standard through the medium of the yoke E the angle of cut may be regulated.

I is a brace-rod pivoted to the standard E, about the center thereof, as at z, and to the under side of the plow-beam, as at t".

Immediately in front of the sweep or plow is secured the pulverizer, which is composed of a V-shaped wooden frame, J secured at its point to the under side of the plow-beam by a yoke or strap, K, which passes around the frame, and its bolt ends 70 passed up through the beam and secured by nuts at the top of said beam, as shown at k,

L is a cross-brace extending from the outer ends of the frame J to the beam A, which forms an additional means of attachment for said frame to the beam, and also braces the ends of the frame from lateral displacement. Around the front and rear edges of the V- frame J is a metal strip, M, which is secured to said frame by the bolts or screws n, that secure the colters or teeth N in position, as will hereinafter appear. The object of this band M is to strengthen the frame and form a This standard is made to curve secure means of fastening the pulverizing or cutting teeth in position. By reason of this construction, the frame being of wood faced with metal, the implement may be made quite light, yet strong and durable.

N are the colters or pulverizing-teeth, secured, one in advance of the other, to the V- frame J by the divided ends N passing alter nately upon opposite sides of the frame J and beneath the metal strips M, and secured in this position by screws mpassing through said strip and ends of colters, and embedding themselves into the wood frame J, as shown at it. These colters are formed with the divided or bifurcated ends N, by which they are attached in position, as above set forth, having a sharp cutting front edge,o, and projecting pointo. A curve in cross-section is also given to these colters or teeth, as shown at 19, Fig. 5, and they are made rights and lefts, in order to more effectually stir the earth, and have a tendency to throw the dirt inward or toward the center. The front edges of these colters are made sharp in order to cut the earth, while the curve given to their back portion acts to pulverize the same by reason of the earth being forced from side to side, because of the form of said teeth. The sweep, then following and cutting slightly beneath the surface, destroys the undergrowth and dusts the plants.

Between the top front portion of the pulverizer-frame and the plow-beam is inserted a wedge-shaped piece, Q, by which'the depth of the cut of the colters or pulverizing-teeth may be regulated. This wedge Q is held in place by the strap K, that secures the frame J to the plow-beam.

Having thus fully described my invention,

its operation, advantages, 8m, what .I claim 1 as new, and desire to secure by Letters Patent .of the United States, is-

1. The combination, in a cultivator, with the handled beam A B O, of the plow or sweep G, with curved standard E, secured at the rear of the beam and adapted for adjustment to gage the angle and depth-of out of the same, V-shaped frame J, also secured to the beam A directly in front of the sweep, teeth N, having a curved body, divided top end, by which they are secured to the frame J, and sharp front edge,'0, and point 0, strap K k, and wedges Q, whereby the pulverizer-frame-may be adjusted vertically to regulate the depth of cut of the teeth, substantially as described,

for the purposes specified.

2. In a cultivator, the combination, with the frame J and metal strip M, of the colters or teeth N, the body of which is curved in crosssection, with a sharp front edge, 0, and point 0, and divided ends N, which ends pass between the said band M and the frame J on alternate edges thereof, and are secured by screws 12, which secure both the band M and teeth N, substantially as described, for the purposes specified.

In testimony whereof I hereunto set my hand in presence of two witnesses.

HENRY PARRISH.
